The pit viper snake genus Trimeresurus Lacépède, 1804 sensu lato , is a diverse group of nocturnal serpents comprising over 61 species. morphologically heterogeneous and has been divided into several subgenera. We present an updated phylogeny Asian pitvipers propose revised classification. Additionally, we revise the taxonomy T. popeiorum Smith, 1937 taxonomic changes with support from molecula...

The concept of a 'deformable arm scale' (completely different from a traditional rigid arm balance) is theoretically introduced and experimentally validated. The idea is not intuitive, but is the result of nonlinear equilibrium kinematics of rods inducing configurational forces, so that deflection of the arms becomes necessary for equilibrium, which would be impossible for a rigid system. In pa...
